Enemy Mine (1985)

At the height of the devastating intergalactic war between humans and the bipedal reptilian humanoids known as Dracs, the earthling single-seat fighter pilot, Willis Davidge, and the saurian pilot, Jeriba Shigan, engage in a furious dogfight. As both sworn enemies crash-land on the desolate, inhospitable planet, Fyrine IV, they will have to put aside their hatred for each other, share knowledge and experience to fight the forces of nature and, above all, work in unison to survive. Can their forced coexistence and uneasy camaraderie pave the way for a genuine inter-species friendship?
